@In tlgrhule :einer tu in tigen trttrrs @ment ma mating nrt nfjlge sume.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ROBERT CHAMBERS, of Cincinnati, Hamilton county,Ohio, have invented a new and useful Improvement in Railroad Rails; andI do hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making part of this specification.

My invention relates to a mode of constructing a railroad rail inseveral pieces in sueh a manner as toloek the Whole together in onecontinuous track, free from liability to either` vertical or lateralprojection at the joints, and capable of being renewed from time to timeat its upper portion as the latter wears.

Figure l is a perspective view ol portions of a compound rail embodyingmy invention.

Figure 2 is a top view of the same.

Figure 3 is a transverse section. Y

My improved rail consists essentially of three parts or sections, ofwhich the parts A and A of precisely similar form constitute the base orweb of the rail, while the part B forms the cap. The inner sides, a a,of the webs A A are slightly convex in their transverse section. Theouter sides, e c, have the represented flaring or dove-tailed form toenter a correspondingAunder-cut groove, which extends along the entirelength of the under side of the cap B. E represents a form of chair usedin combination with the above, the tip, c, of the chair acting inconjunction with the spike D on the other side to press the two heels ofthe web together, and thus to expand the top, thus causing the latter tolock securely within the groove Z1 on the principle of a lewis The partsA A B are of course so arranged as to break joint with each other. 'Thecap Binay be of steel, semit steel, or of case-hardened or cold-rollediron, while the webs A A may be of comparatively inferior material.

I claim as new, and of my invention- 1. The compound` railroad rail A ac, A a c', B secured or locked together by the same spike or spikeswhich fasten the rail to the sleeper or cross-tie, substantially as setforth.

2. In combination with the aforesaid compound rail, I claim thesingle-lipped chair E e.

In testimony of which invention I hereunto set my hand.
